Great vid ..... narrating instead of working at the same time makes a better instruction vid

Nice job!

Thank you🙂

Also, my regulator is in the pump assembly but that is already out so can I test it? Since I've ordered the pump with basic carriage it doesn't have the lid with the regulator on it. Looks permanently fixed in there and I can't find it on autodoc so it may mean sending the bit I've bought back and ordering a whole bigger doodad -- but I'll only know this IF I can test it.
Thanks for reading!

So what about if pressure is steady, but low? Filter has been replaced. I am supposed to see 38 w/ vacuum and 47 without. I get 21 with and 30 without. But it's rock-steady. Need to test if it drops under WOT jolts though

Superb sir.steve from the uk

Thank you🙂

[@chinolocko9429]

Good info, good job man

[@backyardchevy328]

Thank you🙂 i really appreciate it

[@johncollins8304]

Excellent, the only vid I can find testing pressure from the Schraeder fitting. I've found the said fitting but cant find an appropriate hose/connector. Your link doesn't work, and all the other kits don't have a fitting for the S fitting!! My engine starts well but fades out in seconds so presumably wiring is ok. Changed filter. Removed pump and while waiting for new one to come am practising putting it back in. But I would LOVE to test pressure before touching new pump. Another link maybe? Thank you again for the excellent vido!

[@woodybear8298]

His link works fine; it's your computer.

[@chrishemingway4491]

Thought you had to bleed out the extra fuel of that s grader valve before hooking it up

[@rawfoodphilosophy7061]

My pressure is leaking at a medium pace.
Besides checking spark plugs.........how can I test if its flowing back into the tank or a leaking fuel injector?

[@jesusgonzalezpichardo6033]

You can remove the fuel rail with all injectors and hoses still attached if you're able to and turn on the fuel pump and look for any injectors leaking

[@jesusgonzalezpichardo6033]

As far as it goes for the fuel pump itself, it would be safe to assume if your injectors are not leaking and you're having a hard time with the vehicle starting first thing in the morning is probably the fuel pump

[@mrmagoo6178]

what is that silver filter looking thing on fuel rail.

[@backyardchevy328]

thats the fuel pulsation damper, its absorbs any fuel pressure pulsation going into the fuel rail

[@vbmods8945]

question i have same car and im going thru same issue.. i replaced the fuel pump but i need to replace the regulator his can i go about it??

[@backyardchevy328]

Did u just replace the fuel pump and not the assembly? Because the fuel pressure regulator is part of the fuel pump module assembly

[@xzavierfast2v664]

Hey I did the test my the gauge didn’t even read it stayed at 0

[@CesarMartinez-wi7wc]
